To all whom it may concern:

Be it known that I, EMIL JUsLIN, a subject of the Emperor of Russia, anda resident ofthe city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Stopping Apparatus for Railways, of whichthe following is a specification.

My invention consists of an improved stopping apparatus for railwaytrains in which a train will successively during its progress setautomatic stopping apparatus for a subsequent train at given points orblocks when passing such blocks, and simultaneously fully release suchapparatus at a point previously passed, set'and again re-V leased,whereby a subsequent train on the same track will automatically bestopped at the block last set until such block is cleared by thepreceding train passing out of the block into the next succeeding block.

It further consists of means in suchapparatus for releasing from atraveling train a stopping device set by such train in a block next butone to the device being passed, and for partly releasing an apparatusnext but one ahead of the block device being passed and which has beenset train, whereby said apparatus will be prepared to be released by thefirst train when the same passes an apparatus in a subsequent block.

It further consists of means for automatitrain when the lattertrack-section. It further consists of cally setting successive stoppingdevices in successive blocks of a railway track and partly releasing thestopping devices preceding such device from traveling upon the track.

It further consists of such a blocking apparatus in which all of thepower for oper ating the operated apparatus is generated by theoperating apparatus. It further consists of other novel features ofconstruction, all as will be hereinafter fully set forth. 7 r

Referring to the drawings, the numerals 1 indicate the rails atthe innersides of which my improved apparatus is arranged. 'A long box, 2, issupported alongside the rail and has a casing, 3, slidable within it,having a bar, 4, projecting atone end through the open end of saidcasing and formed with a transverse head, 5,; at the'end of the bar. Abolt, an longitudinally slidable'in said casing and has a bevel, 7, atits end and facing the outer side of the sliding casing.

inner side ofthe inner sliding boltf6 ,to have head 5 upon the rodisters withthe same; The other arm of the horizontally movable lockinglever is hooked,

at 14, and extends out of the recess in which it is fulcrumed, and hasplay in a groove, 15, in the inner side of the fixed casing; or box 2,to engage an adjustable stop, 16, across said groove and preferably nearto an opening,

bolt and to engage notches, 19, in the edges of the sides of the slidingcasing without touching the adjustable stop 16. Said forked'head isformed upon the inner end of a bolt, 20, slidablein a radiallyprojecting tube, 21, forming a part of the rigid casing and within whichis a spring, 22, bearing against a collar 23 upon the bolt and againsta'tubular nut, 24, secured in the outer end of the tube. A bolt, 25, issecured in the end of the sliding bolt and is slidable in theend-wall,26, of the movable casing, and said bolt has a spring, 27,coiled around it and bearing against the wall and washers, 28, and ahead, 30, is journaled in the ends of the stationary casing and at theside of the same, and said screw 'is threaded through the adjustablestop 16, to adjust the same lengthwise in the casing.

' Cylinders, 31, are arranged in parallel alinement with the slidingbolt and the sliding and the rigid casings, and pistons, 32, areslidable in said cylinders, and the heads, 33, of said cylinders havepipes, 34 and 35, to' which will later be of the sliding casing, has twolevers, 36, fulcrumed upon its face and near the circumferences, and theouter ends of said levers can engage notches, 37 in rods, 38, extendedtoward the casings at the open inner endsof the cylinders and from thepartitions separating the same, said notchesbeing near the inner 'endsof said guide-rods. rods 38 by notches, '39, in their upper and lowercorners, the yoke being substantially rhombic. Each piston has apiston-rod formed with a conical shoulder, 40, against which the innerend of one of the levers 36, can bearand be pushed outward when passingover it, and said rods have springs, 41, around them which bear againstthe pistons and the facesof the yoke.

A shaft, 42, is journaled transversely to the track and has an upwardlyprojecting arm 43, the upper end of which has a longitudinalslot,'44-,and a rod, 45, is secured to the sliding casing and has alongitudinal slot, 46, which is connected to the rocking bolt, 48,secured through the two arm by a slots; An arm, 49, is secured upon theshaft 42 to be struck by a projection upon the car or.

locomotive passing over it, or preferably by the following means. Atrain-pipe, suitably secured beneath the railway car or 17 in which aforked head, 18, has play to straddle the sliding casing and 29, uponthe bolt. A screw,

straight edge of the cam at referred. The yoke or The head 5 is slidableupon the leased and the shoe in its continued force be tilted whenstruck by the arm 49, to relieve the pressure in the brake-system of thecar and thus apply the brakes on the same, and also cut out steam poweron the locomotive.

A shoe, 64, is secured to a locomotive or car to actuate the automaticstop-device, being capable'of being raised or lowered at will and in amanner not necessary to illustrate, and a bolt, 65, projects outwardfrom said 7 shoe and has a roller, 66, which is adapted to travel on theadjacent rail of the track.

When the device is to be employed, an apparatus like the one describedis placed at the end of each section or blockof the track, alternatelyat opposite sides'of the track and the locomotives of the several trainstraveling on the track are equipped with the shoes and train-pressurereducing apparatus heretofore described.

An apparatus is arranged each section which may be of whatever lengththe block-sections are desired to be, say, for instance at a distance'ofa mile, one from the other.

When now the block at the following section and said section is blocked,the lowered shoe engages the said place and first partly moves the camwhich is held against rotation by the lever engaging the notch in thesegmental edge of the cam.

In describing the operation of the device, it will be assumed that theblocking devices are arranged at one rail of the track and at suitabledistances. apart according to the desired lengths of the block-sections,one de vice being provided at the end of each block. lVith a doubletrack, two series of devices are employed, one for each track.

At the beginning of the trip of a train over a track provided with mysystem, all of the devices are supposed to be in the position seen inFigs. 2 and 8, with the stopping ,levers tilted backward and the severaldevices released and ready to be set.

As the shoe upon the passing locomotive or car strikes the straight edgeof the cam and moves it and the sliding bolt forward, the beveled end ofsaid bolt engages the end of the transverse'latch and pushes the sameoutward, thereby releasing it from the sliding casing which willsubsequently slide for ward with the cam and bolt. When the slid-- ingbolt moves forward, the outer end of the relieving lever 11 engages thestationary stop 16 and saidlever is tilted to disengage from the notchin the cain,.so that, as the shoe moves forward and has pushed the boltand casing forward, such cam will be reat each end of locomotive arrivesat the and movement will tilt the cam downward. As the sliding casingmoves, the cross-head upon the bar compresses the springs upon thepiston-rods which move the pistons in the cylinders and force the liquidin the same, respectively, to a similar apparatus two blocks ahead andtwo blocks behind the actuated apparatus. As soon as the latchleversupon the cross-head arrive at the notches in the guide-rods and thesprings have forced the pistons to the ends of the cylinders to withdrawthe beveled ends of the piston-rods from the lever-arms, saidlatch-levers can rock and have their outer ends engage the notches inthe guide-rods and hold the cross-head, bar, sliding casing and bolt inposition compressing the springs actuating the pistons. that the partsare so arranged and proportioned that their operation is such that thepistons 82=are moved sufiiciently to permit levers 36 to engage with thenotches 37 at a suitable timewith respect to the disengagement of thecam 8 by the shoe 64, it being understood that the movement of thepistons 32 will force the liquid from the cylinders 31 through the pipes34 and 35 respectively.

The forwardly moved sliding casing draws the arm 49 upward, so that itcan engage the arm 5% upon the brake-mechanism of a following train andactuate the brakes to automatically stop the same, if the precedingtrain should not have left its second preceding block. The liquid forcedrearward from the apparatus which has just been actuated by the trainabove described as passing over it acts upon one piston in the apparatusin the second block to the rear and forces the same rearward, causingthe bevel upon the piston-rod to engage and release one latchlever fromits notch and compressing the spring against the cross-head which isstill held by one latch. The liquid which is forced forward from thecylinder of the apparatus described above as operated by the passingtrain, passes to the apparatus in the second block forward and into oneof the cylinders there. If another train which had actuated thisapparatus has passed two blocks forward from the same, such train hasactuated the other piston and forced it backward, in which case the nowactuated piston moves back and the cross-head and sliding casing andbolt move back, giving a clear track and placing the apparatus incondition to be again set. As the cam 8 moves back with the other partsits lower edge rides upon the wallof a slot in the bottom of the boX 2and so is elevated from its position seen in Fig. 4 to that seen in Fig.2.

If the second piston has not been released,

the movement of the last-actuated piston will not release the slidingparts and the apparatus will stay blocked until released by the secondpreceding train.

apparatus two blocks ahead and It will be understood 7 It will thus beseen that a train passing over one apparatus will partly release anlease an apparatus two blocks to the rear to be fully released when thesucceeding train is within two blocks from the same. A train entering ablocked track will be automatically stopped. As it takes one action by apreceding train and one action of a following train to release theblock, the certainty of operation of the apparatus will be assured. aseach operation of one apparatus only partly operates the connectedapparatus.

Instead of a fluid, such'as oil, being employed as the connecting meansbetween the transmittingdevice the latter may be actuated by an electriccircuit without departing from the spirit of my invention.

Other modes of applying the principle'of my invention may be employedfor the mode herein explain-ed. Change may therefore be made as regardsthe mechanism thus disclosed', provided the principles of constructionset forth, respectively in the following claims are employed.
